Description

Technical Field

[0001] This invention belongs to the field of salt industry machinery manufacturing, specifically relating to a salt pond edge cleaning machine and edge cleaning method. Background Technology

[0002] In large-scale salt field production operations, my country currently relies on manual labor to clean the salt foam in the floating roller trenches of salt ponds and to clean the edges of the salt ponds. This manual cleaning is labor-intensive and demanding. Incomplete cleaning of the salt foam in the brine, especially the inadequate removal of silt from the bottom of the floating roller trenches, results in impurities mixed in with the salt foam during the next crystallization process. Consequently, the salt quality fails to meet industry standards, leading to significant waste as the waste product is removed from the salt pond after each cleaning. Furthermore, incomplete manual cleaning of other pond edges results in poor salt crystallization and an increasing amount of salt foam year after year, negatively impacting salt quality. Therefore, designing a salt pond edge cleaning machine and method that can reduce labor intensity, improve production efficiency, and enhance the crystallization quality of the finished salt is of significant practical importance. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the present invention discloses an embodiment of a salt pond cleaning machine and cleaning method that can reduce the labor intensity of workers, improve production efficiency, improve the crystallization quality of finished salt, and increase output through salt foam recovery.

[0004] The technical solution is as follows: A salt pond cleaning machine, comprising:

[0005] The connecting support structure moves within the salt pond following the traction structure;

[0006] The feeding and discharging system includes a salt pump, a feeding structure installed at the input end of the salt pump, and a discharging structure installed at the output end of the salt pump. The feeding and discharging system transfers materials from the edge of the salt pool to the salt pool. The feeding and discharging system is installed on a connecting support structure via a lifting system, and the depth of the feeding structure in the salt pool is adjusted by the lifting system.

[0007] Preferably, the feeding structure includes a feeding pipe and a feeding port.

[0009] More preferably, the traction structure is a tracked traction machine.

[0010] More preferably, the connecting support structure includes a bottom beam, a lifting bracket, and a motor support. The bottom beam is horizontally fixed to the traction end of the traction structure, and the lifting bracket is vertically fixed to the upper end of the bottom beam and reinforced with the traction structure by a support beam. One end of the support beam is fixed in the traction structure, and the other end is connected to the bottom beam. A salt pump and a motor are installed on the motor support, and the motor support is installed on the lifting bracket through a lifting system.

[0011] More preferably, the salt pump is a self-priming salt pump.

[0012] More preferably, the motor and the salt pump are connected horizontally.

[0013] More preferably, the lifting system includes a lifting beam and a hydraulic system for driving the lifting beam to rise and fall, the lifting beam being connected in parallel to the motor support and perpendicular to the lifting bracket.

The lower end of the hydraulic cylinder is fixed to the bottom of the lifting support, and the upper end is fixed to the end of the lifting beam. The hydraulic cylinder is parallel to the lifting support and perpendicular to the lifting beam.

The upper end of the guide plate is perpendicularly connected to the lifting beam, the lower end of the guide plate is perpendicularly connected to the motor support, and the upper end is perpendicularly connected to the lifting beam. The guide wheel is embedded in the lifting bracket and is perpendicularly connected and fixed to the guide plate.

[0016] In a further preferred embodiment, the lifting bracket is provided with a protective plate on the side facing the traction structure. The protective plate is fixedly installed on the lifting bracket and is made of plexiglass.

[0017] The second objective of this invention is to provide a method for cleaning the edges of a salt pond, comprising the following steps:

[0018] Step 1: Connect the support structure and follow the traction structure into the salt pond, so that the feed inlet of the feeding structure is located near the edge of the salt pond;

[0019] Step 2: Adjust the depth of the feeding structure in the salt pond using the lifting system;

[0020] Step 3: The connecting support structure moves along the preset trajectory following the traction structure. During this process, the material on the feed port side is transferred to the discharge port side through the feeding and discharging system.

[0021] Step 4: When cleaning the edge of the salt pond except for the edge where the plastic tarpaulin float is located, transfer the material from the edge of the salt pond to the salt pond through the feeding and discharging system;

Detailed Implementation

[0034] First, it should be noted that the specific structure, features, and advantages of the present invention will be described in detail below by way of examples. However, all descriptions are for illustrative purposes only and should not be construed as limiting the present invention in any way. Furthermore, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the accompanying drawings, can still be arbitrarily combined or deleted among these technical features (or their equivalents) to obtain more other embodiments of the present invention that may not be directly mentioned herein. Additionally, for the sake of simplifying the drawings, the same or similar technical features may be indicated only in one place in the same drawing.

[0035] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," and "screw-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The various embodiments will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] A salt pond edge cleaning machine includes: a connecting support structure that moves within the salt pond following a traction structure; and a feeding and discharging system comprising a salt pump, a feeding structure installed at the input end of the salt pump, and a discharging structure installed at the output end of the salt pump, wherein the feeding and discharging system transfers materials from the edge of the salt pond into the salt pond; the feeding and discharging system is mounted on the connecting support structure via a lifting system, and the depth of the feeding structure within the salt pond is adjusted by the lifting system.

[0038] In this embodiment, as Figure 2-3As shown, the connecting support structure and the feeding and discharging system can move in the salt pond following the traction structure. First, the feeding structure is pulled by the traction structure to position the feeding port of the feeding structure near the edge of the salt pond. Then, the lifting system adjusts the depth of the feeding structure in the salt pond. After that, the traction structure moves along a preset trajectory. During this process, the salt pump transfers the salt foam on the edge of the pond from the feeding port of the feeding structure to the discharge port of the discharging structure, and discharges it into the pond from the discharge port. The salt is then piled up together with the salt collection operation.

[0039] It should be noted that when cleaning the edge of the salt pond where the plastic-covered floating rollers are located, the salt foam and debris in the floating roller grooves on the edge of the pond need to be absorbed and drained into the brine ditch outside the pond for dissolution. The recrystallized salt foam can then be drained into the salt pond using the above method before salt harvesting. Cleaning the floating roller grooves and the edge of the pond at least twice a year helps to increase salt production.

[0040] This salt pond cleaning machine can reduce the labor intensity of workers, improve production efficiency, improve the crystallization quality of finished salt, and increase output through salt foam recovery.

[0041] Furthermore, in this embodiment, the feeding structure includes a feeding pipe 3 and a feeding port 16. The feeding port 16 extends into the salt pool, and the depth of the feeding port 16 in the salt pool is adjusted by adjusting the position of the feeding pipe 3. The feeding pipe 3 is installed at the input end of the salt pump, and the input end of the feeding port 16 is designed with a grid to prevent large foreign objects (such as bricks, stones, etc.) from entering the pump body cavity and damaging the salt pump.

[0042] Furthermore, in this embodiment, the discharge structure includes a discharge pipe 2 and a discharge port, through which salt foam from the pool edge is discharged into the pool. The discharge pipe 2 is installed at the output end of the salt pump via a lockable 360° rotary joint, such as... Figure 3 As shown, when the salt field cleaning machine is used for the first time in the salt pond, the salt in the floating roller ditch contains many impurities, mainly mud, broken brick fragments, and other impurities, and the salt quality does not meet the requirements. Therefore, the discharge pipe 2 and the feed pipe 3 are adjusted to face the same direction and locked in position. The purpose of this installation is to discharge the salt cleaned for the first time into the brine ditch on the edge of the pond, where it turns into brine. After the brine settles and becomes clear, it is then discharged into the salt pond. Subsequently, the salt crystallized in the floating roller ditch meets the quality standards because the mud and impurities in the ditch have been removed in the first operation. The installation direction of the discharge pipe 2 is then adjusted so that the discharge pipe 2 and the feed pipe 3 face each other. When cleaning the floating roller ditch, the salt can be directly discharged into the salt pond.

[0043] Furthermore, in this embodiment, the salt pump can be considered as a self-priming salt pump 1.

[0044] Furthermore, in this embodiment, the traction structure can be a tracked tractor 9, with the hydraulic power system provided within the tracked tractor 9. The connecting support structure and the feeding / discharging system are mounted on the tracked tractor 9 and move with it.

[0045] Furthermore, in this embodiment, the connecting support structure may include a bottom beam 17, a lifting bracket 11, and a motor support 12. The bottom beam 17 is horizontally fixed to the traction end of the traction structure, and the lifting bracket 11 is vertically fixed to the upper end of the bottom beam 17 and reinforced with the traction structure by a support beam 8. One end of the support beam 8 is fixed in the traction structure, and the other end is connected to the bottom beam 17. A salt pump and a motor 4 are installed on the motor support 12. The motor support 12 is installed on the lifting bracket 11 through a lifting system. The lifting system can adjust the lifting and lowering movement of the motor support 12 on the lifting bracket 11, thereby adjusting the depth of the feed inlet 16 in the salt pool.

[0046] Furthermore, in this embodiment, the motor 4 and the self-priming salt pump 1 are horizontally connected, using a 380V plug-in external power supply, and the motor drives the self-priming salt pump to start.

[0047] Furthermore, in this embodiment, the lifting system may include a lifting beam 15 and a hydraulic system for driving the lifting beam 15 to rise and fall. The lifting beam 15 is connected in parallel to the motor support 12 and is perpendicular to the lifting bracket 11. The hydraulic system drives the lifting beam 15 to rise and fall, thereby driving the motor support 12 to rise and fall.

[0048] Furthermore, in this embodiment, the hydraulic system may include a hydraulic lifting control lever 6, a hydraulic lowering control lever 7, and a hydraulic cylinder 5. The hydraulic lifting control lever 6 and the hydraulic lowering control lever 7 are mounted on the tracked tractor 9. The operator can drive the tracked tractor 9 while controlling the hydraulic cylinder 5 to perform lifting movements via the hydraulic lifting control lever 6 and lowering movements via the hydraulic lowering control lever 7. The lower end of the hydraulic cylinder 5 is fixed to the bottom of the lifting support 11, and the upper end is fixed to the end of the lifting beam 15. The hydraulic cylinder 5 is parallel to the lifting support 11 and perpendicular to the lifting beam 15. The lifting beam 15 rises / falls along with the hydraulic cylinder 5.

[0049] Furthermore, this embodiment may also include a guiding system, which includes four guide wheels 13 and two guide plates 14. The upper end of the guide plate 14 is perpendicularly connected to the lifting beam 15, the lower end of the guide plate 14 is perpendicularly connected to the motor support 12, and the upper end is perpendicularly connected to the lifting beam 15. The guide wheels 13 are embedded in the lifting bracket 11 and are perpendicularly connected and fixed to the guide plates 14. When the lifting beam 15 is lifting / lowering, the guide wheels 13 are embedded in the grooves of the lifting bracket 11 and move up and down, playing a guiding role, so that the lifting beam 15 stably drives the guide plates 14 and the motor support 12 to lift / lower.

[0050] Furthermore, in this embodiment, a protective plate 10 may also be provided on the side of the lifting bracket 11 facing the traction structure. The protective plate 10 is fixedly installed on the lifting bracket 11. The protective plate 10 is made of plexiglass and can provide protection without obstructing the operator's view.

[0051] Working Principle: This salt pond cleaning machine includes a tracked tractor 9, a hydraulic power system and operating system provided on the tractor, as well as a connecting support structure, a lifting system, and a feeding / discharging system mounted on the tracked tractor. One end of the support beam 8 is fixed to both sides of the tracked tractor chassis, and the other end is connected to the lifting bracket 11. The lifting beam 15 is horizontal with the motor support 12 and vertical with the lifting bracket 11. The motor and salt pump are horizontally mounted on the motor support 12, and the discharge pipe and feed pipe are respectively installed on the salt pump as required. Hydraulic cylinders are installed on both sides of the lifting bracket 11 as required. The upper end of the cylinder plunger rod is connected to the lifting beam 15 and is in a vertical position. The cylinder plunger rod is vertically connected to the lifting beam 15 on its inner side. The guide wheel 13 is vertically fixed on the guide plate 14 and embedded in the protective plate groove. The depth of the feed inlet in the salt pool is ensured by controlling the hydraulic cylinders to lift and lower according to the thickness of the salt foam. The salt foam on the edge of the pool is discharged into the pool through the discharge pipe by a self-priming salt pump. The mixture of salt foam and brine is discharged into the salt pool through the discharge port. The salt is piled up on the ground during the salt collection operation and collected by other salt collection equipment. This salt pool cleaning vehicle is generally used before the salt collection in spring and autumn. It completely replaces the manual cleaning of the salt pool edge, is highly efficient, cleans the salt foam thoroughly, is easy to operate, greatly reduces the labor intensity of manual labor and improves production efficiency. It meets the requirements of salt industry equipment manufacturing and promotes the technological progress of salt production operations.

[0052] Example 2:

[0053] A method for cleaning the edges of a salt pond includes the following steps:

[0054] Step 1: Connect the support structure and follow the traction structure into the salt pond, so that the feed inlet of the feeding structure is located near the edge of the salt pond;

[0055] Step 2: Adjust the depth of the feeding structure in the salt pond using the lifting system;

[0056] Step 3: The connecting support structure moves along the preset trajectory following the traction structure. During this process, the material on the feed port side is transferred to the discharge port side through the feeding and discharging system.

[0057] Step 4: When cleaning the edge of the salt pond except for the edge where the plastic tarpaulin float is located, transfer the material from the edge of the salt pond to the salt pond through the feeding and discharging system;

[0058] When cleaning the edge of the salt pond where the plastic tarpaulin is located, the material in the groove of the plastic tarpaulin on the edge of the pond is first discharged to the brine ditch outside the pond through the feeding and discharging system to dissolve the brine. Then, the material on the edge of the salt pond is transferred to the salt pond through the feeding and discharging system to meet the cleaning requirements of the four edges of the salt pond, including the plastic tarpaulin.

[0059] The edge-cleaning method implemented by the aforementioned salt pond edge-cleaning machine can clean all four sides of the salt pond, including the plastic-covered floating rollers. As a mechanical, automatic device for absorbing salt foam from the edges of salt ponds, the edge-cleaning machine operates annually before the spring and autumn salt harvests, fully meeting the requirements of the salt production process. When cleaning the edges of the salt pond where the plastic-covered floating rollers are located, the salt foam and debris in the floating roller grooves are absorbed cleanly in the first pass and discharged into the brine ditch outside the pond to dissolve. The recrystallized salt foam can then be discharged into the salt pond before harvesting. The cleaning is thorough and complete. Cleaning the floating roller grooves and pond edges twice a year significantly increases salt production.

Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
